Wilko: Murray's right - he won't win

Andy Murray is recovering from back surgery and if he is to win the Australian Open he will likely need to get past Roger Federer, Rafael Nadal and Novak Djokovic following an unfavourable draw for the Scot.

The man himself says he probably won't win in Melbourne - and ESPN's resident tennis expert and former British No. 1 Chris Wilkinson agrees.

Ferrer, who lost in the semi-finals to Novak Djokovic last year, said: "The last match I played here was very bad, but it's just one match. Now I am in another tournament, other conditions.

"I played well today. I play good some moments in the match and I have to be positive."

The Spaniard's second-round opponent will be Adrian Mannarino, who needed five sets to beat Steve Johnson.

Earlier, Stanislas Wawrinka was the first man through to the second round, advancing after just 15 games when Andrey Golubevretired retired with an injured left leg.

The No. 8 seed Wawrinka, another Djokovic victim in 2013 when he lost 12-10 in the fifth set of the fourth round tie in what proved to be the longest grand slam match of the year, was leading 6-4 6-1 when his Kazakhstan rival quit.

Two other players retired due to shoulder injuries, with Alex Bogomolov quitting after losing two sets to No. 15 Fabio Fognini and 12th seed Tommy Haas pulling out when he was down a set and a break against Guillermo Garcia-Lopez.
